Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545226, here are decompositions:

  • 5 + 31545221 = 31545226
  • 107 + 31545119 = 31545226
  • 257 + 31544969 = 31545226
  • 263 + 31544963 = 31545226
  • 347 + 31544879 = 31545226
  • 443 + 31544783 = 31545226
  • 467 + 31544759 = 31545226
  • 509 + 31544717 = 31545226

Showing the first eight; more decompositions exist.
